HEAD-REST.

i Application filed May 21, 1908. Serial No. 34,079. 1

To all whom it may concern:

Be it known that 1, Josnrrr C. BAHR, citi' zen of the United States,residing at St. Louis, State of Missourn'have invented oer tain new anduseful Improvements in Head- Rests, of which the following is afull,.clear, and exact description, reference being had to theaccompanying drawings, formin'g'a part hereof. v j I My invention hasrelation'to head-rests for barber-chairs (though notv necessarilylimited to the latter) and it consists in the novel constructionandarrangement of parts more fully set forth in the specification andpointed out in the claims;

In the drawings, Figure 1 is a side'elevar tion of a barber-chairshowing my invention applied thereto; Fig. 2 is. a-front elevationof therest in central osition; Fig. 3 is a'similar view showing tie restrocked to one extreme, the front detachable fork-member of therocker-frame being removed; Fig; 4 is' a similar view showing the restrocked to the op osite eXtreme;'and Fig. 5 is a vertical e arged'crosssection-onthe line 5. -5 of Fig. 2. V

The'object of my invention is to construct a head-rest for barber(dentist and similar) 1 chairs which will enable the barber to turn thehead of the person in the chair, without disturbing the position of thehead on the chair, the rest being so mounted that the desired tiltingorrocking' motion may be imparted to the rest without moving the personshead. V

A further object is to construct a rest which will readily conform toany configuration of head su ported by the same, all as will be more fuly apparent from a detailed description of the invention which is asfollows 1-- Y Referring to the drawings, C, represents a conventionalbarber-chair the back of which is provided with a longitudinal socket 1to receive the bar or tongue 2 which carries the rest, as fullyunderstood in the art. The upper end of the tongue 2 carries ananglepiece or bracket 8 whose vertical leg is provided at the ends ofitsupper edge with A wings or abutments 4, l, for a purpose presently toappear. 7 V

The rest is composed of suitably curved longitudinally disposed straps5, 5, terminating in handle-pieces 6, 6, one at each end of the rest,and one handle to each strap), the

Specification of Letters Patent.

middle portions of the straps being connected by a cross-piece 7 withwhich is formed a depending lug 8. Disposed on each side of thetransverse center of the straps 5, 5, are pads 9, 9 made of upholsteredmaterial or they may be pneumatic or inflated sacks. Their adjacent endsare spaced a suitable distance apart so that the continuity between themis broken. By virtue of this construction, the ads or sections 9, 9,will conform themse ves to any outline of head resting against them,each section yielding in proportion to the pressure it may be subjectedto by the weight of the head. A rolling of the head too is prevented,since the head is sup orted on either side of the center, instead at thecenter as would be the case were the sections of the rest madecontinuous or of one piece.

The lug 8 is provided with a hollow boss or spindle'lO carryin ananti-friction roller 11, said spindle being loosely received in a V-shaped slot 12 of the vertical leg of the bracket 3, the lug 8 bearingagainst the rear face of said bracket-leg (Fig. the opposite face of theleg is placed the de- 'tachable Against late 13 which is secured to thehollow spind.e by ascrew 14, the upper edge of the plate resting againstthe under surface of the cross-piece 7. Thus united, the parts 8 and 13constitute a fol'k, whose members are united by the roller-spindle 1Ofreely playing in the V-shaped slot 12. By seizing one of the handles 6and tilting or rocking the rest (from its central osition Fig- 2) in onedirection, the spinde will run up one leg of the V-shaped slot, the edgeof the crosspiece 7 being temporarily fulcrumed against its adjacentabutment 4 (Fig. 3), and when rocked'in the opposite direction, (Fig. 4)the spindle 1O traverses the opposite leg of the V-shaped slot, in whichcase the opposite abutment 4 serves as a fulcrum for the opposite edgeof the cross-piece 7. The occupants head however is not disturbed as itlies in the head-rest, and a person may be shaved first on one side ofthe face, then on the other without necessitating the raising'of hishead off the rest as is now generally done in the case of fixed rests.Where the rest occuples a central position (Fig. 2) the spindle 10 00-Without it being disturbed by any movement the occupant of the chair maymake with his head, the rest only tilting or rocking when actuated bythe barber by seizing the proper handle 6 and drivin the spindle 10 tothe u per end of one of the legs of the \l-shaped s 0t. In this positionthe rest will remain until rocked back to either its central position,or its opposite tilted position. By simply removing the sere'o' 14, theplate 13 Will drop oli, and the rest may be detached altogether by.'itl'l{l1'8,.'-. ing the spindle from the slot 12.

It Will be noticed that the rest does not rock about a centraltransverse axis (r rich axis would be in the plane of section of theline 55 in Fig. 2) but it rocks in one direction about the axis disposedto one side of such central axis, and substantially alongone :i' theside edges of the cross-piece 7, and in the 0 posite direction about anaxis disposed a ong the opposite edge of s at cross-piece; and whileunder those conditions the spindle 10 describes the arc of a circle, theslot 12 fords sullioient play to the spindle to accord it the privilegeof such movement. In its tilted position, the rest is virtually lockedagainst displacement, being supported at two bearing points, the onebearing; formed at the base of one of the inns or abutments 4, and theother by the spindle 1O resting at the upper end of one of the legs ofthe slot 12.

In tilting the rest, the edge oi the piece 7 about which it rocks to 2either of the positions shown in Figs. 0 being located on either side ofthe transverse center of the rest, forms an of rotation for such rest,which axis is obviously dirposed to one side of the transverse center oithe rest. In other Words, tiie axis of lation of the rest does not corrthe central being transverse axis of t is to one side thereof. It isthis a Whicir as a center the rest revolves widen being tilted or rockedto cliang the position of the head of the occupant oi one chair.

Having described my invention, what I claim is 1. In combination with afixed support, a head-rest, means for supporting and tilting a about thesame about an axis disposed to one side of the transverse center of therest, and. means disposed. below the fulcrum about Which the head-restturns for guiding the same in its movements, substantially as set forth.

2. In combination with a fixed support, a headrest, means for supportingand tilting the same about an axis disposed to one side oi thetransverse center of the rest, means for temporarily locking the same inits tilted position, and means dis-gposedv below the fulcrum about whichthe head-rest turns for guiding the same in its movementa, substantially as set forth.

3. In combination with a liXed bracket having a substantially i -seapedslot, a beadrest having a central transverse member, :1. lug; depending"therefrom, a spindle on tit-e lug adapted to tra averse the legs ol theslot, lateral terminal wings on the rixed. bracket projecting; bcvondthe top of the bracket, and allording support to the opposite edges ofthe transverse member, and means for retaining the spindle against\Jltldraval from the slot, substantially as set fortlt.

i. in combination with a lined. bracket raving a substantially if-shapedslot, a beadrest raving a basal centrally disposed transverse member, alug depending tlmrelrom, a lrolloiv spindle projecting from one face oft e lug and traversing the slot, a detachable r secured to the free endof the spindle es ing tlie adjacent face of the bracket, terminallateral wings projecting beyond 0 free edge of the bracket for ni-"aging the opposite edges of her for a central position "'jzer wingserving as a tulcrum-abr 'ient for a rocking movement; of the rest n ntilted. about one of tie edges of the transverse member, the parts operatin; substantially as and for the purpose set for in testimony whereof Iali'ix my signature,

in presence of two Witnesses.
